Higher-form entanglement asymmetry serves as a sub-leading order parameter for 2D Abelian topological order, comparable to topological entanglement entropy and expressible via quantum dimension, with scaling that detects order even in deformed models.
Now we have 2N∂ blocks of matrices having iden- tical unit entries, hence each has one nonzero eigenvalue, thus log 2N∂

Higher-form entanglement asymmetry and topological order
Higher-form entanglement asymmetry serves as a sub-leading order parameter for 2D Abelian topological order, comparable to topological entanglement entropy and expressible via quantum dimension, with scaling that detects order even in deformed models.
